Ingredients for jamie oliver chicken and mushroom tray bake
Five core ingredients transform into Jamie Oliver's signature one-pan umami masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Thighs 🍗 | 1 ½ lb | Cut into even bite-sized pieces |
| Cremini Mushrooms 🍄 | 16 oz | Sliced into even halves |
| Cherry Tomatoes 🍅 | 1 pint | Halved, seeds removed |
| San Marzano Whole-Peel Tomatoes 🍅 | 1 can (28 oz) | Crushed by hand |
| Extra-Virgin Olive Oil 🫒 | ½ cup | Lightly fruity variety |
| Garlic Cloves 🧄 | 4 cloves | Minced, not pre-minced jar |
| Dried Thyme 🌿 | 1 tbsp | Or 1 tbsp fresh thyme leaves |
| Dried Oregano 🍃 | 1 tsp | Mexican oregano preferred |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Cracked peppercorns preferred |
| Balsamic Vinegar 🍷 | 1 tbsp | Aged 25+ months for depth |
| Fresh Rosemary 🌿 | ¼ cup | Needles finely chopped |
| Crusty Baguette 🥖 | 1 whole | For serving, sliced |
The mushrooms are the star here—cremini for meaty texture, but shiitake or oyster work too. Whole Foods or Trader Joe's carry the best fresh varieties, but any grocery store's pre-sliced will do in a pinch. Look for mushrooms with tight gills and no sliminess. The cherry tomatoes? Heirloom colors add visual appeal, but regular reds work just fine. For the tomatoes, San Marzano cans are non-negotiable—they're sweeter and less acidic, which balances the dish perfectly. I grab mine from Costco when they're on sale, but any specialty store carries them.
No cremini mushrooms? White button mushrooms work, but they'll be less flavorful. Short on fresh herbs? Dried thyme and oregano are fine, but reduce to half the amount. The balsamic vinegar can be swapped for red wine vinegar plus 1 tsp sugar if you're out. For the chicken, thighs stay juicier than breasts—bone-in, skin-on if you want extra flavor, but boneless works too. The olive oil matters here—use something you'd drizzle on bread, not the cheap cooking oil. California avocado oil is my go-to for high-heat roasting.
This reheats beautifully—honestly tastes better the next day. Store leftovers in an airtight container for up to 4 days, or freeze for 3 months. I always make a double batch because it disappears fast. The sauce thickens as it sits, so add a splash of water if it seems too dry when reheating. For serving, toast the baguette slices until golden and crispy—perfect for soaking up every last bit of that umami sauce.

Step-by-step instructions for Jamie Oliver's chicken and mushroom tray bake
Here's the foolproof method for a restaurant-quality one-pan dish that delivers deep umami flavors and tender textures every time.
Prep All Ingredients for Perfect Even Cooking
Start by cutting the 1.5 lb boneless, skinless chicken thighs into even bite-sized pieces—about 1-inch cubes. This ensures they cook uniformly and develop crispy edges. Pat them dry completely with paper towels; moisture is the enemy of good browning.
Slice the 16 oz cremini mushrooms into even halves. Remove stems from the 1 pint cherry tomatoes and halve them, then squeeze out any seeds. Crush the 1 can (28 oz) San Marzano whole-peel tomatoes by hand—this prevents a watery sauce later. Finely chop the 0.25 cup fresh rosemary needles and mince the 4 cloves garlic. Here's the thing—fresh herbs and garlic make all the difference in this dish.
Build Flavor Layers in the Tray
Preheat your oven to 400°F. In a large oven-safe skillet or baking dish (I use a 12-inch cast-iron skillet), heat 0.25 cup of the extra-virgin olive oil over medium-high heat. Add the chicken pieces in a single layer and let them sear undisturbed for 4-5 minutes until golden brown on one side. Flip and repeat on the other side—don't crowd the pan or they'll steam instead of crisp.
Remove the chicken and set aside. In the same skillet, add the remaining 0.25 cup extra-virgin olive oil and the sliced mushrooms. Cook for 5-6 minutes until they release their moisture and begin to brown. Add the minced garlic and cook for 30 seconds until fragrant—this prevents bitter garlic flavors. Stir in the dried thyme, dried oregano, 1.5 tsp diamond crystal kosher salt, and 0.5 tsp freshly ground black pepper, letting them toast for 1 minute to deepen their aroma.
Assemble the Umami-Packed Tray Bake
Return the seared chicken to the skillet and arrange it in an even layer. Add the halved cherry tomatoes and crushed San Marzano tomatoes, spreading them evenly over the chicken and mushrooms. Drizzle with the 1 tbsp balsamic vinegar and sprinkle with the chopped fresh rosemary. The acidity from the vinegar will brighten the dish while the rosemary adds a piney depth that ties everything together.
Here's where it gets fun—toss everything gently but thoroughly with tongs to distribute the juices and aromatics. The goal is to coat every piece of chicken and mushroom with the tomato mixture. If the pan looks dry, add 1-2 tablespoons of water to help the flavors meld without making it watery.
Bake Until Golden and Tender
Transfer the skillet to the preheated oven and bake uncovered for 25-30 minutes. You're looking for the chicken to reach an internal temperature of 165°F and the mushrooms to be tender with golden edges. The tomatoes should burst slightly, releasing their juices and creating a glossy sauce that clings to everything.
I know it's tempting to peek, but resist the urge—every time you open the oven, you risk losing heat and steam, which can make the chicken dry out. Instead, trust the timing and check the doneness by testing the thickest piece of chicken with a thermometer. If it's not quite there, return it to the oven for 5-10 more minutes.
Serve with Crusty Baguette
Remove the tray bake from the oven and let it rest for 5 minutes—this allows the juices to redistribute so every bite is moist and flavorful. Real talk: the sauce will thicken as it cools, so don't worry if it looks a bit loose when it comes out of the oven.
Slice the 1 whole crusty baguette into thick pieces and serve alongside the tray bake. The crusty bread soaks up the delicious sauce while adding a satisfying contrast to the tender chicken and mushrooms. Each bite should deliver a perfect balance of savory, umami-rich flavors with a touch of bright acidity from the tomatoes and balsamic.
Pro Tips For Making Jamie Oliver Chicken And Mushroom Tray Bake
- HALVE THOSE MUSHROOMS: Cremini mushrooms shrink hard—cut them into ½-inch slices, not thick rounds. I learned this after serving a tray bake where half the mushrooms looked like hockey pucks. Even thickness means even cooking, and that’s how you get the golden, tender bite Jamie’s after.
- SALT THE CHICKEN FIRST: Season the chicken thighs before they hit the tray—at least 20 minutes ahead. I used to skip this, thinking it’d get soggy, but the salt actually helps break down the proteins for juicier meat. (Yes, even if you’re impatient like me.)
- SKIP THE CROWDED TRAY: Spread the chicken and mushrooms in a single layer—no overlapping. After three batches where the edges stayed raw, I realized the tray bake needs airflow. If it looks sparse, it’s working.
- CRUSH THOSE WHOLE PEELS: San Marzano tomatoes? Rip open the peels with your fingers and crush them lightly before adding. It’s the only way to get that jammy, saucy texture without turning it into a watery mess. (I know, I know—it’s not the prettiest method, but it works.)
Flavor customization for this dish
Herb Variations
Swap out the rosemary for fresh thyme if you prefer a more floral note—just use 1 tbsp fresh thyme leaves instead of the rosemary. For a Mediterranean twist, add 1 tsp dried basil and ½ tsp dried marjoram to the dried herb mix.
I once made this with fresh sage from my garden, and the earthy aroma took it to another level. 🌿
Spice Level Boost
For heat lovers, add ½ tsp crushed red pepper flakes to the dried herb mix or finish with 1 tbsp hot honey after baking. If you want smoky depth, sprinkle ½ tsp smoked paprika over the chicken before baking.
I keep a jar of Penzeys smoked paprika in my pantry—it adds that authentic BBQ campfire flavor without overpowering.
Creamy Upgrade
Stir in ¼ cup heavy cream or ½ cup Greek yogurt with the tomatoes for a richer sauce. The cream will create a velvety coating on the chicken and mushrooms. For a lighter option, use ¼ cup coconut cream—it adds a subtle sweetness that balances the umami perfectly. 🥛
Cheesy Finish
Sprinkle ½ cup grated Parmesan or pecorino romano over the top during the final 5 minutes of baking. The cheese will melt slightly, creating crispy golden bits that add texture contrast. I also love adding ¼ cup panko breadcrumbs mixed with 1 tbsp melted butter for extra crunch.
Vegetable Add-Ins
Add 1 diced red bell pepper or ½ cup chopped kalamata olives to the tray for extra texture. Roasted garlic cloves (4 whole cloves, peeled and halved) add sweetness as they caramelize.
For a heartier dish, toss in ½ cup diced butternut squash—it soaks up the sauce beautifully. 🍠
Protein Swaps
Replace chicken with 1 lb shrimp or 1 lb firm tofu for a seafood or vegetarian version. If using shrimp, sauté them until just pink (2-3 minutes) before adding to the tray.
For tofu, press and cube it first, then pan-fry until golden before baking. I’ve also made this with chicken sausage for a meatier texture.

Frequently asked questions
Can I use white button mushrooms instead of cremini?
Yes, but expect less flavor depth. White buttons work in a pinch, though cremini mushrooms have a meatier texture and richer umami. For best results, use 16 oz cremini or substitute with 8 oz cremini + 8 oz oyster mushrooms to boost earthy notes. The dish will still taste great, just slightly milder.
How do I prevent the chicken from drying out?
Pat the chicken pieces completely dry before searing, and don't overcrowd the pan. Cook in batches if needed. After baking, let it rest for 5 minutes before serving—this redistributes juices. For extra moisture, add 2 tbsp water to the pan before baking or cover loosely with foil during the last 10 minutes if your oven runs hot.
What's the best way to reheat leftovers?
Reheat gently in a skillet over medium-low heat for 5-7 minutes, adding 1 tbsp water or broth to prevent drying. Microwaving works too—cover with a damp paper towel and heat for 1-2 minutes. The sauce thickens when cold, so add a splash of water if needed. Leftovers actually taste better the next day!
Can I make this ahead of time?
Assemble the tray bake up to 24 hours ahead, cover tightly, and refrigerate. Bake straight from cold at 400°F for 35-40 minutes, adding 5 minutes to the original time. For make-ahead meals, this is perfect—just reheat as directed above. The flavors develop beautifully overnight.
What if I don't have San Marzano tomatoes?
Use any high-quality canned tomatoes, but avoid chunky varieties. Crush them by hand to prevent a watery sauce. For extra depth, add 1 tsp tomato paste or a pinch of sugar to balance acidity. The dish will still turn out flavorful, though San Marzano's natural sweetness is ideal.
